Hey – happy to help — if you don’t mind, if you could give an example of a specific page or part of the book / specific game involving chains that is causing you trouble, and, if you’d like, just a bit of information about the type of trouble you are having, it would help me try to figure out better how to be useful to you — I think I know generally what you are asking about, but lesson 14 covers a few different things and I want to make sure I address your specific concerns — thanks — mk
